IMPROVEMENT IN AXLE-TREES.

TO ALL WHOM IT MAY CONCERN:

Be it known that I, JAMES V. WILKIE, of Auburn, in the State of New York, have invented certain new and useful Improvements in A. ;le-Treos; and I do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the accompanying drawings, and to the letters of reference marked thereon, in whichi Figure 1 represents a. side view of the axle and box.

Figure 2, a section of the same, showing the manner in which ouch part is constructed,and their relative position to each other when properly adjusted.

Figure 3 represents an end view of the box; and

Figure 4 the divided nut.

The peculiarities of this invention consist in forming n neck on the inner portion of the arm, and in the employment of n divided nut, which encircles and revolves around said neck by being screwed into the box, substantially as hereinafter set forth.

In order that others skilled in the art may make and use my invention, I will now describe its construction.

A represents the axle, which is formed with the flange or shoulder a on its arm, as fully seen in fig. 2, thus leaving a neck between said finngc and the inner portion of the arm. B represents the box, which it will be observed is solid at its outer end. A female-screw is cut in its opposite end, which extends almost to a shoulder formed on the inside of said box, as shown in fig. 2. (t represents a. divided nut, each part formed, as seenin ,iig. 4. The length of this nut should correspond with that of the neck, in order that when the parts are properly adjusted there will be no lateral play; said nut should encircle and revolve around the neck on the arm by being screwed into the box B, as seen in fig. 2. he advantages which are derived from thus constructing an axle are obvious: first, there can be no accident arising from the wheel running ofi, because of the nut coming unscrewed; second, there can no dirt or sand work in between the box and arm; and third, its convenience and perfect simplicity.

Having thus fully described my invention, what I claim, and desire to secure by Letters Patent, is 1. The employment of a divided nut, as and for the purpose set forth. 2. The employment 0i a. divided vnut, in combination with the arm of the axle, as constructed, as and for the purpose described.

3. The box as constructed, in combination with a divided nut, substantially as set forth.
